Title: Production of perpendicular magnetic recording medium
Inventor: HINOBAYASHI TAKEO
IPC: G11B5/738
Filed: 1990-03-05
Abstract: PURPOSE:To prevent the degaussing, erasing, etc., of magnetization information on a perpendicular recording layer by floating magnetic fields by implanting nonmagnetic or magnetic conversion ions to an underlying layer according to the exposed parts thereof to impart the shape anisotropy in a recording track direction to the regions for recording and forming the perpendicular recording layer over the entire surface on the underlying layer after the ion implantation. CONSTITUTION:After the underlying layer 22 is formed on a nonmagnetic disk substrate 21, a mask 24 for ion implantation to be disposed concentrically with the regions 26 for recording having the width of the recording tracks on the underlying layer 22 is formed along the regions corresponding to these tracks. The nonmagnetic or magnetic conversion ions are implanted to the underlying layer 22 according to the exposed parts thereof via the mask 24 for ion implantation to impart the shape anisotropy in the recording track direction to the regions 26 for recording. The perpendicular recording layer 27 is formed over the entire surface on the underlying layer 22 after the ion implantation. The degaussing, erasing, etc., of the magnetization information recorded on the perpendicular recording layer 27 by the floating magnetic fields are prevented in this way.

Title: Method for formation of trench isolation in integrated circuit
Inventor: PARK TAI-SU
IPC: H01L21/76
Filed: 1999-03-02
Abstract: PROBLEM TO BE SOLVED: To obtain a method in which the etch rate of a sidewall insulating film is made lower than the etch rate of a trench insulating film, by a method wherein a heat treatment is executed at a low temperature in such a way that the etch rate of the trench insulating film is maintained to be higher than the etch rate of the sidewall insulating film. SOLUTION: At a stage at which a sidewall insulating film 9 and a trench insulating film 11 are formed, the trench insulating film 11 is formed in such a way that its etch rate is higher than the etch rate of the sidewall insulating film 9. A stage at which the sidewall insulating film 9 is formed on the bottom and the inner sidewall of a trench, and a stage at which the trench insulating film 11 is formed inside the trench, are classified into four sub stages. First, the sidewall insulating film 9 is grown on the bottom and the sidewall of the trench. Lastly, a semiconductor substrate is treated at a temperature of 150 deg.C or lower. In this heat treatment stage, the etch rate of the trench insulating film 11 is reduced.  When the heat treatment stage is maintained at 1050 deg.C or lower, the etch rate of the trench sidewall film 11 becomes larger than the etch rate of the sidewall insulating film 9.

Title: Capacity measuring device for copying machine
Inventor: SHIRAI MASARU
IPC: G03G21/00
Filed: 1985-03-19
Abstract: PURPOSE:To measure automatically the first copy time capacity and the copy start capacity and to make high-reliability measurement possible by providing a sensor means, a time counting means, and a display means. CONSTITUTION:When a test original G is set and a start switch 2 is depressed, a microcomputer 7 starts counting-up of a counter C and stops counting-up when the rear end of a copy paper Y passes under the first sensor 4. The value of a first copy time Tc is calculated by multiplying the held value of the counter C by a time per one count. When ejection of the second copy paper Y from a copying machine X is started, counters D and E are counted up. When a mark Ya appears from the copying machine X, counting-up of the counter E is stopped, and the counted value of the counter E indicates a time corresponding to a length l from the edge of the second copy paper Y to the longer side of the mark Ya. The counted value of the counter D indicates a time from the eject completion time of the first copy paper Y to that of the 11th copy paper Y.

Abstract: PROBLEM TO BE SOLVED: To ease mirror retaining accuracy so as to facilitate production and reduce production cost by moving a reflection mirror so that a photographing lens may be switched, and allowing only one reflection mirror to intervene in image forming luminous flux. SOLUTION: The photographing lenses 8 to 10 possess focal distances for tele(T), middle(M) and wide(W), respectively, and the focal distances are made longer as they go away from a CCD 13. Then, they are respectively formed as lens blocks 8b to 10b and housed in the recessed parts 18 to 20 of a lens mirror holding part 12. The reflection mirror 21 to 23 provided corresponding to the optical axes of the lenses 8 to 10 respectively bend the image forming luminous flux in a photographing optical path leading to the CCD 13 from the lenses 8 to 10. By turning the mirrors 22 and 23, the lenses 8 to 10 are switched. In such a case, only one of the mirrors 21 to 23 intervenes in the image forming luminous flux leading to the CCD 13 from the respective lenses 8 to 10.

Title: Image forming device
Inventor: SHIMONO MAMORU
IPC: G03G15/00
Filed: 1987-03-12
Abstract: PURPOSE:To permit connection and driving of an exhaust fan and driving motor by means of a piece of driving belt and to reduce the number of parts and cost by using a revolving shaft of the exhaust fan in common use as a fulcrum shaft for upper and lower units. CONSTITUTION:The revolving shaft 36 of the exhaust fan 33 is commonly used as the fulcrum shaft to pivotally support the lower units 31, 32 freely turnably. The upper unit 31 opens and closes around the revolving shaft 36 of the exhaust fan 33. The exhaust fan 33 does not, therefore, move and exists in the home position even if the upper unit 31 is opened and closed. The distance between the exhaust fan 33 and the driving motor 34 is thereby maintained always in the specified state and the exhaust fan 33 can be rotationally driven simply by putting on a piece of the driving belt 38. The number of parts and the cost are thereby reduced.

Abstract: PROBLEM TO BE SOLVED: To provide an MOS type solid-state image pickup device by which an object to be reproduced is not deformed due to movement of the object in the horizontal direction or the like by reading an electric charge of plural photo diodes simultaneously thereby reducing the time difference of image pickup timing of each picture element, and to provide a method for driving the device. SOLUTION: A unit cell is composed of a photo diode 1, an amplifier transistor(TR) 2, an address capacitor 33, a transfer TR 34, and a detection section 35, the address capacitor 33 is connected between the detection section 35 and a horizontal address and a gate of the transfer TR 34 is connected to a transfer signal line 32. The transfer TR 34 reads signal charges of the photo diode 1 simultaneously from all picture elements and gives them to the detection section 35 and they are stored in the address capacitor 33. Since the signal charge stored in all the photo diodes 1 are simultaneously read in the address capacitor 33 of each unit cell, the time difference in the image pickup timing of each picture element is reduced.

Title: Conductive paste
Inventor: OKUNOYAMA TERU
IPC: C08K3/02
Filed: 1988-03-11
Abstract: PURPOSE:To reduce sedimentation of conductive powder so as to enhance adherence thereof by providing the title paste comprising high purity resin, a diluent having low viscosity and copper conductive powder having a silver coating layer on its surface as essential components. CONSTITUTION:High purity resin, a diluent having low viscosity and conductive powder having a silver coating layer on its surface are mixed. Namely, the high purity resin is dissolved in the diluent, and as required, both components are partially bonded to each other by the effect of thermal reaction. The copper conductive powder having the silver coating layer on its surface is added thereinto so as to be sufficiently mixed therewith, followed by a kneading process by means of, for example, a three-roll and a vacuum degassing process, thereby obtaining the conductive paste. This enables whole ion concentration to be reduced and corrosive disconnection not to be liable to be generated. Therefore, low specific gravity and little sedimentation of the conductive powder result in improvement in adherence and hydrolitic resistance.
